Be it known that I, HUBERr VVITTE, a citi-- zen of the United States,residing at the city- 'of St. Louis, State of Missouri,.have invent- 1ed a certain new and useful Improvement in Car-Seats, of-which thefollowing is a full, clear, and exact description, such as will en ableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification, in which Figure 1 is an end elevation. Fig. 2 is afront view, partly in section, on about the line 2 2 of Fig. 1 of oneend of the seat; and Fig. 3 is a fragmentary detail, thesupporting-lever being removed and certain of the parts being brokenaway; i v

This invention relates to improvements in car-seats, my object being toprovide a seat of simple and convenient construction and of easyoperation.

To these ends and also to improve generally upon devices ofthe characterindicated the invention consists in the various matters hereinafterdescribed and claimed.

Referring n. w more particularly to the drawings, 1 indicates an endsupport ore-asting. 2 is a saddle pivoted upon said end support at 3,and 4 is the seat proper, which is supported upon the saddle in anyconvenient or well-known manner. The seat-back is connected tocarrying-levers 5, and these carrying-levers are pivotally connected tothe upper ends of supporting-levers 6, the lower ends of saidsupporting-levers being pivoted at 7 upon the end supports belowthe-seat proper and in substantially the transverse cen ter of theseat.,

2:, Foi'ined upon the inner sideof each end'plate 1 is a segmental rack8, and above this r a'ck a segmental slot 9 is formed in each end plateA shaft 10 extends between thesuppbrting levers 6 and isrotatablymounted in them."

Gear-blocks connected to this shaft to -rotate" therewith have each asubstantially -.cylindrical portion 11, which extends through one;

of the before-mentioned segmental slots 9,.

and upon each side of this cylindrical portion is a gear, the inner gearbeinglmarked 12 and the outer gear 13; The inner gear meshes with thebefore-mentioned segmental rack 8 while the outer gear meshes with asegmental rack l hformed upon the lower end of the backcarrying lever 5.p A

- \Vhen in either extreme, position, the cylindrical portion 11 of eachgear-block engages one end of the segmental slot 9, andthlecarrying-lever 5 is-upon one'side of the "seat-,- proper in position togive the deslredinclr' j nation to the back, while the jack 14 is inmesh with the pinion or'gear 13 When force is applied to the seat-backin adirectioutoward the opposite side of the seat, the lever 5cannothave its upper end rocked forwardly, upon the pivotal connectionbetweensaid le-rf ver and its supporting-lever 6, for the lever 5 canrock only upon movement of the gear.- block, and movement of saidblockto permit forward rocking of the upper end of the seats I back isprevented by reasonot' the fact that the cylindrical portion ot thegear-block engages one end wall of the slot 9 and the gear 12 is in meshwith the rack 8. When, therefore, force is applied to the seat-back'in adirection tending to move said back toward the opposite side of theseat, the supporting-lee ver 6 rocks upon its pivot 7 and the gears ofcourse move bodily with said supporting-le ver. 'As thegear-block'movesitoward the op posite side of the seat the cooperationbetween the rack 8 and the pinion 12,causesthegearblock to be rotated,and suchrotationof'the f pinion 1 3, meshingwiththdrack 14, causes, the'carrying 'l'ever' 5"to be. rocked upon itsa -*pivota1 connection? withthe supportingflever' 6, the inclination otthe carrying levergand ..v

tion.

consequently oftheseauback,beingfreversed' as the seat-back is throwninto its new os'i gear-block being of sutiicient length to extendthrough not only the slot 9 of the end support, but also the saidcam-slot 15 of the adjacent saddle-plate. Therefore as thecarrying-lever 6 swings from one side to the other of the seat the saidcylindrical portion 11 of the gear-block cooperates with the wall ofits.

receiving cam-slot 15 to rock the saddle upon its pivot, and thusreverse the inclination of the seatproper in a manner which will bereadily apparent.

Extending from the lower portion of each supporting-lever 6, andpreferably integral in a manner which will be clearly apparent as theseat-back is thrown from one side of the seat to the other thereof.

I am aware that minor changes in the construction, arrangement, andcombination of the several parts of my device can be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle of my invention.

Ipivoted, a gear carried by said supporting Having thusdescribed theinvention, what is claimed as new, and desired to be secured by LettersPatent, is

1. In a car-seat, the combination'with a sea I proper, a seat-back,rockable levers arranged on each side of the back for pivotallysupporting the same, seat-tilting members carried by saidback-supporting levers, and aconnection between the back below itspivotal point and said seat-tilting members for tilting the back inopposite directions and for causing each of the seat-tilting members toalternately con-' tact with a portion of the seat near its respectivelongitudinal edges whereby said seat will be tilted: substantially asdescribed 2. In a car-seat, the combination with a'seat proper, and aback movable from one side of the seat to the other thereof, of amovable supporting member upon whichsaid back is membeiya rack overwhich said gear travels as said supporting member is moved from 7 oneside of said seat to the other thereof, a

rack upon said seat-baek a nd operative conneetion between said rack andsaid gear; substantially as described.

- 3'. In a car-seat, the combination with a'seat proper, and aseat-back, of a Si! DDOrting-lever to-which said seat-back ,is pivo ,agear carried by said supporting lever, a rack over which said gearmoves, a rack upon said 'on each side of ing the same,

supporting levers to which rotary motion is imparted when the levers aremoved,said memseat-back, and operative connection between said rack andsaid gear; substantially as de-' scribed.

4. In a car-seat, the combination with a seat proper, and a'seat-backmovable from one side of said seat to the other thereof, of a movablesupporting member to which said seat-back is pivoted, a gear carried bysaid supporting member, a rack over which said gear travels a secondgear connected to said first gear, and a rack upon said seat-backcooperating with said second gear; substantially as described.

5. In acar-seat, the combination with a relatively fixed member providedwith a slot, a seat proper, and a seat-back movable from one side ofsaid seat to the other thereof, of a supporting member to which saidseat-back is pivoted, a revolving pinion carried by said supportingmember, a rack over which said pinion travels from end'to end, operativeconnection between said pinion and said seat-back for rocking the latterupon its pivot, and a member connected to said pinion and received insaid slot, whereby the walls of said slot serve to limit the movement ofsaid pinion; substantially as described.
